Patented Sept. 20, 1932 GEORGE GOBER, or ALAMEDA, CALIFORNIA TOGGLE BOLT Application filed February 29, 1932. Serial No'. 595,757.

This invention is a toggle bolt and-has special reference to a togglev bolt for use on blind plates or sheets, where no access can be obtained to the inside of the plate or sheet and where the sheet is too thin to permit tapping for a stud.

In many cases it is found desirable to attach name plates and other devices to a surface in which the metal is too thin to permit tapping and where no access can be obtained to the rear surface. Such cases may occur where an illuminated sign has been installed and possibly an additional character is desired, or it may be desirable to attach a plate or device to the body of an automotive Vehicle, in which the body plate is made of thin material, usually 26 or 28 ga. steel and no access can be gained to the inside of the plate without removing the cushioning material, lining and other supporting means.

It is for such purposes that the present invention was evolved..

The main object of the invention, therefore, is to provide a toggle bolt which is particularly adapted for providing securing means on blind sheets or plates, where the interior surface of the plate is not accessible.

Another object of the invention is to provide a bolt as outlined which is automatically 3 locked against rotation when installed and which may be readily removed and replaced in the event of the breaking of a bolt or stripping of threads.

Other objects and advantages of the in- V vention will become apparent as the following description is read on the accompanying drawing and in which similar reference characters are used to indicate similar parts throughout the several views and in which Fig. 1 is a longitudinal view of the bolt showing the plate in section.

v Fig. 8 isan end View of Fig. 7. Fig. 9 is a section taken on the vertical `The invention consists of a bolt 10 provided with an integral elongated head 11 adapted to pass through an aperture 12 in aplate 13.r` f

The locking member 14 is freely mounted G0 on the bolt 10 and also elongated and adapted to lit inthe 'aperture 12,and has a transverse slot-15 fo-rmed inthe bottom surface which is adapted to receive the bolt head 11 transversely and prevent rotational movement thereof. lntegral with or secured to the topI of the locking member 14 'is a member 16, the edges 17 of which project-to, cooperate with the outer surface of the sheet to prevent its passing l throughthe aperture, the locking member exclusive of member 16 being thicker than the plate 13, so as to extend through the plate to cooperate with the' head 11. Y

A nut 18 is threadedly cooperative with the bolt 10Y and has a recess 19 formed therein to clear the member 16. y V T he device is installed by passing the head 11 through the aperture 12 which-has been previously formedv in the sheet, settingthe locking member 1.4 in the aperture, then Y drawing ythe boltout and turning it until the head 11 seats in slot 15, after which the nut 18 is drawn down tigh f The modification shown in Figs. 3 to 6 is adaptable for use with standard boltsor machine screws and is a toggle nut," consisting of a base member 20v having an integral hub'21 centrally tapped as at 22 to receive a standard bolt` orV screw and recessed as shown at 23 and adapted to pass through the aperture 24 in the plate. The cooperating member 25 is rotatably mounted on the hub 21 and has integral ears 26,k formed thereon to cooperate with the recessed 'portions .23 of 95 the base member 20 and` is adapted to fit within the Yaperture 24 in plate 27. A flange member 28 is ,secured-onhub 21 and retains member 25 onfthe hub, pre-vents this member `from passing throughthe aperture, and

provides means for rotating the base member 20 transversely of the aperture 24.

The installation of this device requires the provision of an elongated aperture, after Which the members are aligned as shown in Fig. 6 and inserted through the aperture, member 25 tting Within the aperture and retained by the iange v28 from passing through, While member 2O clears the other side of the plate and is turned until the sides of member 2O cooperate or are stopped against further rotation by ears 26.

Another modification shown in Figs. 7,' '8 and 9 is similarly operable to the previously described nut but is formed integral With the bolt 30, the head 31 being elongated and adapted to pass through the elongated aperture in plate 32, and being recessed as at 33, being similar in form to member 2O except transversely to the ma] or axis of the locking member and means adapted to prevent said locking member from passing through said aperture.

4. In combination with a plate having an elongated aperture formed therein; bolt securing means for said plate comprising a threaded element, engaging means adapted to pass through said aperture and engage the plate When'turned transversely and retainingmeans non-rotatable in said aperture and adapted to retain said engaging means in transverse relation thereto and provided hvvith means engaging the front of the plate vfor preventing the passage of the retaining means throughthe aperture. v

as to the hub. Locking member 34 is pro-VV vided With ears 35 and is adapted to fit Within the aperture in plate 32 With the ears v35 projecting to cooperate withv member 31,

and is rotatably mounted on the bolt r30. A collar 36 is suitably mounted and v.retained by a shoulder 37 on the bolt 30. j

This device is merely inserted in the plate aperture With the head 31 extending through the aperture and member 34 disposed' Within the aperture, and the bolt rotated until the head 31 is stopped by ears 35.

Having described an operative device, and

various modifications thereof, it will be un.V

derstood that variations in 'construction and arrangement of parts Which are consistent With the appended claims may be resorted to Without detracting from the spirit or scope of the inventionor sacricing any of the advantages thereof.

I claim: a

1. In combination With a threaded element, an elongated first member adapted to be passed through anl aperture in a plate, an elongated second member adapted tofit into said aperture and provided With means for retaining said elongated first member in transverse relation to the major axis of the second member and means for preventing passage of said second member through said aperture.
